According to US

Doctor Daguerrotype is stealing the world's most famous landmarks by using his magic camera that makes them disappear into the photographs. All they have to do is develop the photos and the landmarks will become real in their wold. They can go back and forth between worlds because they had photographed the door and can use it when they want. He tries to photograph Rick but Rick manages to dodge him.  Just imagine how many times Rick has been photographed since then.  Rick tries to warn Miss Tickle not to let the door close behind her, because she wouldn't be able to get back out.
Doctor Daguerrotype and his sidekicks continue to chase everyone around trying to get their pictures. The song ties in with this episode since they are going to have to figure out how to get to the other side.  A lot of running and chasing happens. Finally Dotor Daguerrotype and his sidekicks get photographed by their own camera trap. Rick and Miss Tickle develop all the film they need to get everything back to normal.
